What is Photo Chemical Etching?

Photo Chemical Etching (PCE)—also known as photochemical machining (PCM)—is a precision metal manufacturing process used to create complex, burr-free metal parts by selectively dissolving metal with a chemical etchant, guided by a photographic mask. Why Choose Photo Chemical Etching? Photo chemical etching is ideal when you need tight tolerances, intricate designs, and clean edges—especially for thin metal parts where traditional stamping or laser cutting may cause burrs, heat distortion, or high tooling costs.

Key Advantages of Photo Chemical Etching:

• High precision & fine detail (micro holes, slots, intricate patterns)

• No tooling or mechanical stress—no burrs or deformation

• Fast prototyping & low setup cost compared to stamping

• Design flexibility—easy to modify artwork

• Consistent quality for both small and medium production runs

How Photo Chemical Etching Works

1. Metal preparation
   A thin metal sheet (e.g., stainless steel, copper, brass, nickel, titanium) is cleaned and coated with a light-sensitive photoresist.

2. Photo imaging
   A phototool (artwork) containing the part design is aligned on the metal and exposed to UV light, transferring the pattern to the photoresist.

3. Developing
   The exposed or unexposed photoresist is removed (depending on resist type), revealing precise areas of bare metal.

4. Chemical etching
   The sheet passes through an etchant (such as ferric chloride), which dissolves the unprotected metal to form the required geometry.

5. Resist stripping & finishing
   Remaining photoresist is stripped, and optional finishing processes (polishing, plating, passivation, forming) are applied.
